Used in biomedical research to quantify levels of pulmonary surfactant protein C in biological samples, aiding in the study of lung function and diseases such as respiratory distress syndrome, interstitial lung disease, and other pulmonary disorders. Enables researchers to assess alveolar epithelial cell integrity and surfactant metabolism in experimental models. Commonly applied in preclinical studies, clinical diagnostics development, and monitoring disease progression or therapeutic response in lung-related conditions.
